Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Xerophytes
Concept: Plant xeromorphic structural adaptations.

Solution: Xerophytes live in arid conditions. Sunken stomata trap moist air within epidermal depressions, reducing the water vapor concentration gradient and minimizing transpiration.

Why other options are incorrect:
  • Option A: Mesophytes live in moderate water environments and have surface stomata.

  • Option B: Hydrophytes live in water and often have stomata on upper leaf surfaces or lack them.

  • Option D: Halophytes are adapted to saline soils.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
